COMPOSITION FENCE-POST.

Specification of Letters .Patent. Pafontefl Nnv, 25-, 1 91 3,

V Application filed August 13. 1912. Serial No. 714,920.

To all 20110221 1' i may concern Be it known that I, Rt'ssELL B. IiEYNETT, citizen of the United States. residing at I 'esterville, in thecounty of Franklin and State of Ohio, have invented certain new anduseful Improvements in Composition F ence-Posts, of which the followingis a specification. I

This invention relates to the manufacture of composition posts, moreparticularly of 1 the type shown in Letters Patent No.

829,940, granted to me September 4, 1906. The objects of the presentinvention are to produce a post of vpronounced,durability and strengthwith minimum quantity of material, to provide a reinforcement which willnot be displaced during the molding of the post and in which thelongitudinal elements will be held in fixed relation; and to provide areinforcement of truss-like form which will not interfere with the insertioh of the staple-receiving composition.

The invention consists in certain novel features. all of which will behereinafter first fully described and then more particularly pointed outin-the claim following the description.

The invention is illustrated in the accompanying drawings, in which:

. Figure 1 is a perspective View of a reinforcement for compositionposts showing the parts of the same assembled before the post is formedaround the same; Fig. 2 is a transverse vertical section of a moldshowing a post formed therein; Fig. 3 is a detail plan view of adifferent form of brace or spacer for use in the reinforcement; Fig. 4is-a transverse section of a mold showing a postformed therein andprovided with a further form of reinforcement; Fig. 5 is a detailperspective view of the reinforcement shown in Fig. 4; Figs. 6, 7, and 8are detail plan views of different forms of spacers.

In carrying out my invention, I employ a plurality of longitudinal rodsor braces 1 which may be of any desired number according to the outlinedesired for the finished post. I prefer to make the posts substantiallytriangular in horizontalsection, as I have found that this form avoidsunnecessary weight and bulk, while possessas clearly shown, thereinforcing rods passing through openings provlded therefor at theangle-and at the ends of the spacers.

In Figs. 1 and 2, the spacers are shown as provided near their ends andin their outer edges with notches 3 whereby shoulders 4 are formed, andon their inner edges at their ends they are rovided with theenlargements 5 where y sufficient metal is 4 formed around therod-receiving opening to support. the rod and prevent the detachment ofthe spacer therefrom.

The reinforcement, consisting of therods or bars and the ties or spacersfitted thereon, is placed within a mold 6 which is approximatelytriangular in cross section, and the concrete or other cementitiouscomposition? is poured in to the mold so as to entirely fill the samearound the several elements of the reinforcement. It will be readilynoted upon reference to Fig. 2 that the shoulders or corners 4: of thereinforce ment engage the lower -downwardly converging walls of the moldso as to support the reinforcement in proper spaced relation to the moldand permit the plasticcomposition to entirely fill the space between thereinforcement and the side of the mold so that the metallic members ofthe reinforcement will be entirely inclosed by and embedded in thecomposition of the post. The mold will, of course, beof a lengthcorresponding to the height desired for the post,

' and the longitudinal reinforcing bars will be located at the cornersof the post and will extend the full length of the same.

The'spacers or tles, by which the longitudinal reinforcing rods or barsare held in their proper spaced relation within the mold while the postis being poured, may be of various forms and I have shown several whichrove efiicient. In Fig. 3, the spacer is su stantially of the same formas that shown in Fig. 2, except that on its outer edges, near its angle,it is provided with outstanding spurs .01 teeth 8 and inits inner edge,adjacent its lower end or its angle, notches 9 are provided. In the formshown in Fig. 6, two spurs or teeth 10 are formed on the outer edges ofthe spacer and two notches or recesses-11 are formed in each inner edgethereof. In Fig.,7, is shown a form of spacer in which the recess 3.indicated in the previously described forms, is omitted, and theshoulder 12 springs directly from the straight outer edge of the spacer.In this form, also, the enlargement 13 is reduced toward the end of thespacer and is disposed at an obtuse angle thereto in its lower portion,instead of being s'emicircular, and the opening-14, to recelve thebracing'rod, is somewhat lower in the spacer. In Fig. 8,-- the spacer isshown without the enlargement on the inner edge thereof, the

- straight edge 15 of the end of the spacer being reduced and the inneredge 16 thereof being straight.

The several forms of spacers just de;

scribed are. easily stamped out of sheet metal, and, with the exceptionof the formshown in Fig. 7, a. large number of the spacers maybefistamped from a single strip of metal without any waste, while in theform shown in Fig. 7 may be produced with only so much waste as will beincluded between the lines of the inner edges of the main portion ofthe'spacer "and the highest point of the enlargements 13. It is notslightly necessary, however toemploy sheet metal contact with the bottomof the mold and the composition for the post may be poured into the moldso as to flow entirely around the members of the reinforcement.

It will be readily noted from the foregoing description, taken inconnection with the accompanying drawings, that I have provided aconstruction in which it will be impossible to displace the members ofthe reinforcement during the molding of the post and that thepost may berapidly and cheaply produced, and when produced, will be efl'e'ctuallyreinforced-at the oints where the strain is usually applied t ereto. Thelongitudinal reinforcing bars, which will be apex an ment, as thedistance between the ties or spacers is short, and it will,consequently, be practically impossible to break the post. The spacercannot buckle, as it is held firml within the concrete, and any strainwhic would tend to force apart the rods passing through the ends of thespacers must first crush the concrete below the point where the strainis applied, and this strain will be resisted by the tensile strength ofthe spacer at its angle.

As the ties or spacers are V-shaped or have open tops, they offer noobstruction to the pouring of the cementitious material into the moldnor do they interfere in any degree with the proper location of thestaple-receiving composition strip, indicated at 21. I

What I claim is:

A fence post comprising a substantially triangular body, a plurality ofV-shaped spacers embedded therein and having their sides substantiallyparallel with the faces of the body leach spacer. having an eye at its dat each terminal and provided with a supporting projection on each outerside near each terminal, said projections constituting suspending pointsdisposed between' the terminals and the apex of the spacer, rodsinserted through and inclosed and supported by the eyes in the s acers,and a penetrable composition in one ace of the body between theterminals of the spacers. In testimon whereof I aflix my signature inpresence-o two witnesses.
